Abstract
Description
L'invention concerne un moyeu de roue de véhicule automobile comportant un palier à corps roulants disposé dans un logement dudit moyeu et un dispositif capteur d'informations dont l'élément codeur est solidaire en rotation du moyeu et se déplace devant un capteur fixe.The invention relates to a wheel hub of a motor vehicle comprising a rolling body bearing disposed in a housing of said hub and an information sensor device the encoder element of which is integral in rotation with the hub and moves in front of a fixed sensor.
La publication FR.A.2 570 143 décrit un tel moyeu dans lequel l'élément codeur est fixé à la périphérie externe du moyeu sensiblement dans le plan d'un chemin de roulement du palier.The publication FR.A.2 570 143 describes such a hub in which the encoder element is fixed to the external periphery of the hub substantially in the plane of a raceway of the bearing.
Lorsque le moyeu est solidaire d'un tambour de freinage qui délimite avec la périphérie externe du moyeu le logement de frein, l'élément codeur ne peut plus être placé sur le moyeu. Par ailleurs, lorsque le palier à corps roulants est un roulement conventionnel placé dans un moyeu accolé au porte-fusée sur lequel est fixé le plateau de frein, le dispositif capteur ne peut plus satisfaire à l'agencement précité, en raison du faible espace disponible.When the hub is integral with a brake drum which defines the brake housing with the outer periphery of the hub, the encoder element can no longer be placed on the hub. Furthermore, when the rolling body bearing is a conventional bearing placed in a hub attached to the stub axle on which the brake plate is fixed, the sensor device can no longer satisfy the above arrangement, due to the small space available. .
L'invention a donc principalement pour objet un moyeu de roue pour freins à tambour facilitant le montage d'un capteur de vitesse dans le but de permettre par exemple, la réalisation d'un dispositif d'antiblocage de roues et/ou d'antipatinage pour véhicules équipés de freins à tambour.The invention therefore mainly relates to a wheel hub for drum brakes facilitating the mounting of a speed sensor in order to allow for example, the realization of an anti-lock device and / or traction control for vehicles fitted with drum brakes.
Selon l'invention, l'élément codeur est intégré de préférence dans le joint d'étanchéité du palier à corps roulants de telle façon qu'il affleure sensiblement dans le plan d'une face latérale du moyeu tournée vers le plan longitudinal du véhicule, l'élément capteur, solidarisé avec un support fixe par rapport à la roue, étant disposé coaxialement à l'élément codeur dans une position radiale sensiblement égale à la valeur du rayon de l'élément codeur et décalée longitudinalement d'une valeur maximale correspondant à l'entrefer autorisé par la technologie du capteur mis en oeuvre.According to the invention, the encoder element is preferably integrated in the seal of the rolling body bearing so that it is substantially flush with the plane of a lateral face of the hub facing the longitudinal plane of the vehicle, the sensor element, secured to a fixed support relative to the wheel, being arranged coaxially with the encoder element in a radial position substantially equal to the value of the radius of the encoder element and offset longitudinally by a maximum value corresponding to the air gap authorized by the sensor technology used.
On décrira ci-après un mode de réalisation du moyeu en référence au dessin annexé dans lequel,
- - la figure 1 est une vue en coupe axiale du moyeu de frein à tambour monté sur une fusée de roue non motrice de véhicule automobile selon la ligne 1.1. de la figure 2.
- - la figure 2 est une vue de face du moyeu suivant la flèche F de la figure 1.
- - la figure 3 est une vue à une plus grande échelle du détail III de la figure 1.
- - la figure 4 est une vue à une plus grande échelle du même détail III avec un agencement différent de la liaison entre le capteur et son support.
- - Figure 1 is an axial sectional view of the drum brake hub mounted on a non-driving wheel spindle of a motor vehicle along line 1.1. in Figure 2.
- FIG. 2 is a front view of the hub according to arrow F in FIG. 1.
- - Figure 3 is a view on a larger scale of detail III of Figure 1.
- - Figure 4 is a view on a larger scale of the same detail III with a different arrangement of the connection between the sensor and its support.
Un moyeu de roue non motrice comporte une fusée 10 débouchant à l'extérieur d'un porte-fusée 11 et portant à son extrémité filetée, l'écrou 12 et la rondelle de mise en contrainte axiale d'un palier 13 qui peut être à deux rangées de corps roulants 14 disposés entre une bague intérieure 15 fractionnée en deux parties et une bague extérieure 16 dont les extrémités portent respectivement un joint d'étanchéité 17.A non-driving wheel hub comprises a
Le palier 13 peut être constitué de 2 roulements conventionnels sans sortir pour autant du cadre de la présente invention.The
Le palier 13 est disposé dans un logement 21 constitué par l'alésage d'un moyeu tournant 20 qui se prolonge radialement par un tambour de frein 23 dont la face extérieure porte les goujons de fixation non représentés de la roue du véhicule.The
La bague extérieure 16 du palier est immobilisée dans le moyeu 20, radialement par serrage et axialement entre un épaulement 24 du logement 21 et une rondelle d'arrêt portée par le moyeu.The
Selon l'invention, un dispositif capteur 25 d'informations, notamment de la vitesse de rotation de la roue, est constitué par un élément codeur 26 solidaire en rotation du moyeu 20 et d'un capteur 27 fixe. L'immobilisation de l'élément codeur 26 est avantageusement réalisée par intégration au joint d'étanchéité 17 au moment du moulage de ce dernier de telle façon qu'il soit positionné en regard de l'élément capteur. Tel que représenté dans la fig. 1, l'élément codeur affleure la face latérale externe du joint d'étanchéité. Selon une variante de l'invention (fig. 4), le support 28 du codeur 26 est une bague comportant une rainure circulaire dans laquelle est logé l'élément codeur 26 et ce support est placé dans le logement 21 de sorte que le codeur soit situé sensiblement dans le plan de la face latérale 22 du moyeu tournée vers le plan longitudinal du véhicule. Le support 28 possède à cet effet, un bord 30 radial annulaire susceptible de faciliter son immobilisation par pincement entre le flanc de la bague 16 du palier et l'épaulement 24.According to the invention, an
La solidarisation entre l'élément codeur et son support peut être réalisée par d'autres moyens sans pour autant sortir du cadre de l'invention.The connection between the encoder element and its support can be achieved by other means without departing from the scope of the invention.
Le support 29 de l'élément capteur 27 est constitué par une plaque en matériau de préférence non magnétique, rendue solidaire d'une bague 30′ fixe montée sur la fusée 10 entre la bague intérieure 15 du palier et le porte-fusée 11. Le support 29 est agencé de telle façon que son positionnement angulaire par rapport au plateau de frein soit assuré. Dans l'exemple représenté fig. 2, le support 29 comporte une série d'encoches 31 qui assurent cette fonction en coopérant avec les vis de fixation 33 du plateau de frein 32. Par ailleurs, le support 29 est conçu de telle façon qu'il n'existe qu'une seule et unique possibilité de positionnement angulaire favorable au fonctionnement correct de l'élément capteur 27. De manière à s'affranchir de la variation d'entrefer entre l'élément codeur 26 et l'élément capteur 27 engendrée par le dévers angulaire de la roue selon son plan de symétrie vertical durant les virages, l'élément capteur 27 est positionné selon une direction horizontale A - A′ telle que représentée en fig. 2.The
Le support 29 de l'élément capteur 27 a pour fonction complémentaire de supporter un circuit imprimé 27′ comprenant les éléments de protection de l'élément capteur 27 contre les surtensions et les inversions de polarité. En outre, il assure le maintien efficace du câble 27˝ qui transporte les signaux vers la centrale de traitement en traversant le plateau de frein 32, en coopérant avec un élément 34 qui assure l'étanchéité contre la pénétratïon de pollution à l'intérieur de l'enceinte du frein.
Sans sortir du cadre de l'invention, il est bien évident que le dispositif capteur 25 peut être de tout type connu, bien que l'on ait décrit à titre d'exemple aucunement limitatif, le capteur en référence de la demande de brevet 86.08348 déposée en France au nom de la demanderesse.The
Without departing from the scope of the invention, it is obvious that the
De même, l'invention n'est nullement limitée au mode de réalisation décrit et représenté, donné à titre d'exemple. En particulier, elle englobe les moyens équivalents techniques des moyens décrits ou leurs combinaisons si celles-ci réalisées dans l'esprit de l'invention ou mises en oeuvre dans le cadre d'une prise d'informations de la vitesse d'un moyeu tournant.Likewise, the invention is in no way limited to the embodiment described and shown, given by way of example. In particular, it includes the equivalent technical means of the means described or their combinations if these carried out in the spirit of the invention or implemented in the context of taking information about the speed of a rotating hub .
